5 Claims.

The present invention relates to apparatus for cooling and dispensingliquids such, for example, as beverages of various kinds andparticularly beer, ale, and the like.

One object of the invention is to provide in combination with a beveragedispensing bar, improved means for cooling or refrigerating beer, ale,and other beverages, which is so combined with the bar as to afford aunitary and compact structure and one in which common refrigeratingmeans is provided for cooling both the bar and the beverage holdingcontainers or receptacles as well as the tubes or pipes for deliveringthe beer to the dispensing faucets.

A further object of the invention is to provide in apparatus of thisclass, a combined serving counter and storage compartment affording ineffect a single refrigerating unit, having space for articles of food,bottled beverages, and a series of barrels or other receptaclescontaining the beverages, together with pipes or tubes for deliveringthe beverage to the dispensing faucets.

A further object of the invention is to provide the receptacles withdelivery pipes of glass or vitreous material for conveying the beer andother beverages therefrom through a single cooling chamber containingthe receptacles to the dispensing faucets of the bar in order to avoidthe deteriorating and displeasing effect upon the beer resulting fromallowing it to stand for a considerable time in the usual metal pipes,employed for discharging it to the dispensing faucets as well as toavoid the loss made necessary from having to draw off and discard aconsiderable quantity of the beer after it has been allowed to remainWithin the pipes over night.

A further object of the invention is to deliver the beer or other liquidthrough the refrigerating chamber of the serving counter to thedispensing faucets by means of transparent pipes and to provide a windowor glass panel in one or more of the walls of the serving counterwhereby to render the pipes and the liquid therein visible at all times,as well as to make it possible to view the interior of the storagecompartment containing the beer barrels or other beverage holdingreceptacles, in order that inspection may be made by the customer orothers to determine whether or not sanitary conditions are beingmaintained.

A further object of the invention is to provide in combination withfront and back bars, a compartment below the level thereof for thebarrels vor beverage holding receptacles and in which a unitary beveragecooling and dispensing bar of insulated construction, including an upperserving section and a combined storage and refrigerating section belowthe floor of the bar, as, for example, in a cellar beneath the same, thebar having one or more refrigerating chambers communicating with saidcompartment and the latter having a refrigerating unit associatedtherewith together with means for circulating the cold air therein andin said chambers for the purpose described.

A further object of the invention is to provide in combination with abeverage dispensing bar having a cooling chamber and a communicatingrefrigerating compartment beneath the same for beer barrels and otherbeverage containers. a series of liquid dispensing pipes connected withthe barrels and extending therefrom through said compartment and saidcooling chamber and each including a plurality of sections havingflexible connections by which the sections may be disconnected andadjusted or deflected one relative to another to facilitate insertion ofthe lower sections through the bungs or bushings of the barrels, wherebyto avoid having to so position the barrels with respect to the pipes asto accurately line up the openings of the bungs therewith.

A further object of the invention is to provide an improved bung orbushing for the barrel through which to insert the beer delivery pipeand one having improved means for automatically closing the openingtherein when the pipe is withdrawn from the barrel, and also improvedmeans affording a sealed joint between'the tube and the bushing.

To these and other ends the invention resides in certain improvementsand combinations of parts, all as will be hereinafter more fullydescribed, the novel features being pointed out in the claims at the endof the specification.

The same reference numerals throughout t -e several views indicate thesame parts.

Referring to the drawings I!) represents the floor and H certain of theside walls of a room containing the bar, the latter being designatedgenerally by the reference numeral 12. Beneath the floor I0 is a cellaror basement :3, the floor of which is indicated at 13a, one or more ofthe side walls of the cellar being shown at M, Figs. 1 and 2. Supportedby the floor l3a is a refrigerating compartment i having top and bottomwalls l6 and H, side walls l8, and end walls [9, all formed of suitableinsulating material for maintaining substantially uniform temperatureswithin the compartment, which constitutes a cooling chamber [5a, in opencommunication with thecooling chamber |2a of the upper or servingsection [2 of the bar, the latter having front and rear walls 20 and 2|an upper horizontal wall 22, and also inner and outer end walls 20a. and2|a, respectively, each formed of suitable insulating material.

The compartment I5 is provided with a door l9a in one of its end wallsfor closing and opening, provided to render the compartment accessibleand through which the beer barrels 23 or other beverage holdingcontainers or receptacles may be inserted and removed from time to time.

A back bar is shown in Fig. 2, designated generally by the referencenumeral 25 and has a cooling. chamber 26 in open communication with thecooling or refrigerating chamber Ilia of the compartment 15. The wallsof the back bar, including the door 21, are formed of suitableinsulating material. The cooling or. refrigerating chamber 26 isprovided with a plurality of shelves 28 for supporting bottledbeverages, dishes, and other articles as well.

The front wall of the serving counter i2 is provided with a window ortransparent panel 29 preferably formed of a plurality of sheets of glasshaving insulating spaces 29a therebetween to prevent fogging of theglass, whereby to render the interior of the compartment I211 and thebarrels therein visible. Suitably secured within said compartment are aplurality of shelves 39 for supporting the beverage containing bottles3| or other articles which it may be desired to place within thecompartment and which can be readily viewed through the window 29. Thecompartment l2a, is also provided with a door 32 for closing an openingthrough which to insert the articles to be placed upon the shelves 30.By providing the transparent panel or window 29, bottled beverages ofvarious kinds and other articles as Well may be displayed to advantagewithin the refrigerating compartment lZa from time to time.

An important feature of the invention resides in the manner ofconstructing and arranging the pipes or conduits for conveying the beerfrom the barrels 23 to the dispensing faucets 33. The pipes are formedof glass or vitreous material for a purpose more fully describedhereinafter, it being understood that any desired number of the pipesmay be provided, depending on the number of the barrels or beverageholding receptacles to be used, five being shown in the presentinstallation.

Owing to the fact that it is desirable to locate the dispensing faucetsfor the various pipes relatively close together, it is necessary tooffset the opposite ends of each of a majority of the pipes, as shown inFig. 1, and it is preferred to form each pipe of separate sections andto connect the sections by means of flexible or resilient couplings topermit one to be deflected relative to another in order to avoid havingto so position the barrels as to accurately aline the openings of thebungs with the lower sections of the pipes. Furthermore the sections areso constructed as to permit one to be readily disconnected from anotherin order that the lower section may be removed from the barrel when itis desired to substitute a full barrel for an empty one. The lowersections of the pipes are designated generally by the reference numeral34, and the couplings for connecting them with the upper or intermediatesections by the reference numeral 35, these parts being the same in eachcase, for which reason a description of one will sufiice for all. Theconstruction of the delivery pipes and the manner of connecting themwith the barrels is best shown in Figs. 6, 7, and 8.

Each of the pipes, with the exception of the second from the left inFig. 1 includes in addition to the inner sections 34, an intermediatesection 36 and an outer section 31, the intermediate and outer sectionsbeing connected by couplings, as shown in Fig. 1, which are of similarconstruction except where they differ in length, the two short couplingsbeing indicated at 35a, and the next in length at 35b, and the longestat 35c. It will be further understood that the couplings connecting theouter and intermediate sections of the pipes are the same as thecouplings 35, except in cases where they are of different lengths. Theinner or lower section 34 of the second pipe from the left of Fig. 1 hasonly one upper section connected therewith which is also designated bythe reference numeral 31. Furthermore, the lower sections 34 of thepipes are provided with similarly constructed valves 38 for controllingthe flow of the liquid through the pipes. The lower sections 34 of thepipes each includes upper and lower glass tubes 39 and 40, respectively,which are separated by and suitably connected with the valve 38 bysimilarly constructed packing nuts 4| screwed on the threaded portions38a of the valve between which and the end wall of the nut is a gasket41a formed of rubber or other suitable material. It will be understoodthat by tightening up the nuts 4| that the gaskets will be compressedand made to tightly grip the glass tubes without danger of breaking thesame, but under suflicient pressure to firmly secure the tubes inposition upon the body of the valve and at the same time affording aliquid-tight joint between the tube and the valve body. The packing nutsare each preferably provided with an elongated sleeve-like portionMbwhich is spaced slightly from the tube and which serves to preventswinging of the latter about its point of connection with the nut 4|.The joints between the opposing ends of the tubes and the valve 38 areeach sealed by a washer 38b formed of rubber or other suitable material,the washers being disposed within the threaded portions 38a of thevalve, as shown in Fig. 7. i

The sections 40 of the glass tubes which are extended through the bungs24 are provided. with inlet openings 40a, as shown in Figs. 6 and 7through which the beverage enters the pipes for discharge to the faucetsunder pressure of air or gas in the barrel which is delivered theretothrough a supply hose or tube 24a connected with a suitable supplysource, not shown.

The lower couplings, designated generally by the reference numeral 35,serve to connect the glass tubes 36 and 39 as best shown in Fig. 8. Eachof the couplings comprises a short glass tube 42, the opposite ends ofwhich are each extended within a packing nut having inner and outersections 43 and 44, respectively, the latter being threaded within theformer, as shown in Fig. 8. The opposite ends of the glass tube 52 arebeaded, as shown at 42a, the beaded portions being each seated on a ring45 screwed within the section 43 of the packing nut. The opposing endsof the glass tubes 35 and 39 are extended through the packing nuts andeach is surrounded by inner and outer gaskets 45 and 41, respectively.The gaskets are formed of rubber or other suitable material and areinterposed between the outer member 44 of the packing nut and theopposing end of the glass tube 42 on which end the gasket 45 is seated.By screwing down the section 44 of the packing nut the rubber gaskets 5and 31 will be compressed and made to tightly grip the glass tubeswhereby they will be properly held against longitudinal movement onerelative to another. However, due to the resiliency of the gaskets thetubes may be readily deflected one relative to another and relative tothe couplings, as indicated by the position of the tube 39 shown in Fig.8. Since this is true, it will be seen that all of the couplings shownin Fig. 1 are provided with sufliciently flexible joints to make itunnecessary to have to so position the barrels as to exactly aline theopenings in the bungs thereof with the lower portions of the deliverypipes. In other words, the flexibility of the joints of the pipes issufficient to permit of an approximate alinement of the bungs of thebarrels with the pipes whereby to avoid the necessity of having to takethe time and trouble to place the barrels exactly in the same positioneach time it becomes necessary to substitute new barrels for those fromwhich the beer has been drawn.

A further advantage in the provision of the flexible couplings is toprevent breaking of the glass tubes in case pressure is applied to one,accidentally or otherwise in a direction tending to deflect it out ofalinement with another. Since the several couplings shown in Fig. l varyonly in length and since the construction of each is substantially thesame as that shown in Fig. 8, it is deemed unnecessary to furtherdescribe the details, of the same.

The upper glass sections 31 of the pipes have their outer ends 31aextended through and disposed at right angles to the rear wall 2| of thecounter or serving section of the bar, as shown in Fig. 5, said endseach being disposed in a short pipe section 48 also extended throughsaid wall. The pipe section is secured in position within said wall bythe inner and outer nuts 49 and 5!] which are screwed upon said pipesection and in engagement with the opposite faces of the wall, as shownin Fig. 5. The glass tube is resiliently supported on the inner end ofsaid pipe section by a rubber gasket 5| carried by a nut 52 threaded onsaid section which serves to clamp the gasket thereon.

Screwed on the outer end of the pipe section 48 is the dispensing faucet33 which carries a resilient packing ring 53 surrounding the outer endof the glass tube and seated on the end of the pipe section 48. The tubeis beaded at 54 and is held against withdrawal from the pipe section byengagement of the bead with the resilient gasket 53. A set screw 55serves to hold the faucet in position upon the inner section 48. Belowthe faucets 33 is a shelf 55 for the drinking glasses or otherreceptacles which it may be desired to place thereon.

The outer glass tubes 31 of the delivery pipes are placed relativelyclose together, as previously stated, and directly opposite the same thefront wall of the bar is provided with a window 51 preferably formed ofa plurality of glass plates having insulating spaces 51a therebetweenwhich serve to prevent fogging of the glass.

A similar window 58 is provided in the top wall of the bar directly overthe outlet ends of the delivery pipes, as shown in Figs. 1 and 4, saidwindow having a plurality of sheets of glass separated by insulatingspaces 58a, which also serve to prevent fogging of the glass.

It will be understood that the interior of the refrigerating compartmentand the barrels and pipes therein may be readily viewed by lookingdownwardly through the windows 29, 51, and 58 whereby the customer maybe informed as to the sanitary conditions of the compartment containingthe beverage holding receptacles.

One of the important features of the invention is the use of the glasstubes or pipes for discharging beer, ale, and other beverages from thebarrels or kegs to the dispensing faucets. Not only are the glass tubesmore sanitary than the usual metal or block tin tubes or coils throughwhich the beer is discharged to the faucets, but they also make itpossible to avoid the waste resulting from having to draw off the beerremaining in the metal tubes over night, due to the deteriorating anddispleasing effect of the latter on the beer when it is allowed to standtherein for any length of time. However, where glass tubes are used thebeer remains fresh and palatable even when retained within the tubes fora considerable period of time, especially when the tubes are disposedwithin a cooling chamber as in the present disclosure. Furthermore, ithas been found that the cost of the beer which it becomes necessary todiscard when the usual metal pipes or coils are installed is veryconsiderable over a period of time. However with the use of glass tubesthe loss by wastage is reduced to a minimum and a consequent saving iseffected.

Another advantage of the use of las ery tubes is that the beverage therin in i ge readlly viewed by the customer through the windows 5"! and58, provided in the front and upper horizontal walls of the servingcounter and the tubes inspected from time to time by the attendant to'determine whether or not the tubes have become discolored or stained tosuch an extent as to make it advisable to wash them out by forcing asuitable cleaning agent therethrough.

Any suitable refrigerating means may be provided for cooling thecompartment containing the beer holding receptacles and therefrigerating chambers of the front and back bars communicatingtherewith. The means provided for this purpose in the present disclosurecomprises a cooling coil 6| disposed in an open ended frame or casing 82suitably secured within the cooling chamber |5a of the compartment l5,preferably adjacent one end thereof, as shown in Fig. 1. The coil isconnected by means of the pipes 63 and 64 with a suitable refrigeratingunit 65 of any well known type adapted for circulating a refrigerantthrough the coil. In order to properly distribute the air cooled by thecoil 8|, a fan 66 is disposed at one end of the casing 82 containing thecoil, the fan being connected with and adapted to be rotated by anelectric motor 67 to force the air from the casing into the coolingchamber l5a.

In order to insure proper circulation of the air within the chambers ofthe front and back bars, an outwardly and upwardly inclined deflectingplate 68 is disposed at the bottom of the casing 62 which serves todirect a considerable portion of the air discharging from the casingupwardly within said chambers, which are at all times in opencommunication with the barrel holding chamber I50.

The new and novel construction of the bung for the barrel and associatedparts, is shown in Figs. 9 to inclusive. The bung, designated generallyby the reference numeral 24, comprises a threaded disk screwed into thehead 23a of the barrel, as shown in Fig. 6. The disk is provided with anopening 69 terminating at its inner end in an inwardly and downwardlyinclined seat or shoulder 19 upon which is disposed the correspondinglytapered portion ll of a valve supporting member 12, the latter beingextended slightly below the disk 24, as shown in Fig. 10. The supportingmember 72 is provided with a tapered opening 14 within which a portionof a ball-shaped valve 15 projects for closing the bung opening throughwhich the glass tube 48 is inserted and withdrawn from the barrel. Thevalve is supported by an arm 16 loosely connected with the valve by ascrew '51 threaded within the valve and extended through an opening inthe arm of slightly larger diameter than that of the screw, as shown inFig. 13. The arm is pivotally connected at 18 with a bracket 19 suitablysecured upon the supporting member 72. A U-shaped spring 89 has itsmiddle portion extended under the arm 76 and its end portions wound uponthe ends of the pivot member 18, as shown in Fig. 12. The spring tendsat all times to urge the valve upon its seat 73, but when the glass tube49 is moved downwardly through the opening in the bung, the valve willbe displaced, as shown in Fig. 14. As soon, however, as the tube 48 iswithdrawn from the barre] the spring will automatically return thelatter to normal closing position, as shown in Fig. 13.

The glass tube 40 is yieldingly supported within the barrel by a rubbergasket or packing ring 8| seated on the supporting member 12 upon whichit is clamped by a nut 82 threaded within the disk 24, as shown in Fig.14. By screwing down the nut the rubber gasket will be made to tightlygrip the tube 48 whereby to prevent escape of the air or gas from thebarrel supplied by the tube 24a to provide pressure for discharging thebeer upwardly through the delivery pipes to the faucets. The nut 82 isrecessed at 83 for the reception of. a wrench or suitable tool foroperating the same. The rubber gasket 8| is resilient enough to permitthe valve to efiect a tight closure of the bung opening when the valveis in engagement with its seat 13 formed on the lower face of the gasket8|.

The disk 24 is provided with an opening 84 for the reception of the airsupply tube 24a, the opening being normally closed by a valve 85supported within a casing 86 and normally held in closed position by aspring 81, the inner end of which is seated upon a screw cap 88detachably connected with the casing. The valve seat is formed on arubber gasket 89 held in position upon the casing 86 by a nut 9|]threaded within the disk 24, as shown in Fig. 10, the nut having slots9| for the reception of a suitable tool for applying and removing thenut. The valve casing 86 has an outwardly flared portion 86a at itsupper end which is seated on a correspondingly shaped shoulder 86b ofthe disk 24.

The free end of the air supply pipe 24a is of a size to afiord arelatively close fit within the gasket 89 when inserted therein, asshown in Fig. 11, whereby to prevent escape of the air from the barrel.Upon withdrawing the pipe from the opening 84, the spring 81 willautomatically move the valve to closed position, as shown in Fig. 10.The disk 24 is provided with openings 92 in its outer face for thereception of a spanner wrench or other suitable tool for applying thedisk to and removing it from the head 23a of the barrel.

When it is desired to remove the glass tubes 48 from the barrels afterthe latter have been emptied, the nut 82 of the bung will be loosened torelieve the pressure on the gasket 8|, after which the nut 44 at thelower end of the coupling 35 may be loosened to relieve the pressure ofthe gaskets 46 and 41 on the tube 39, following which the nut 4| abovethe valve 38 may be unscrewed from the latter to free the tube 39 formovement upwardly within the tube 42 of the coupling 35 far enough toclear the upper threaded portion 38a of the valve. The empty barrel canthen be removed and the tube 48 withdrawn therefrom and inserted in afull barrel. When the barrel has been properly placed with respect tothe delivery pipe, the tube 39 can be moved downwardly to position itslower end within the upper threaded portion of the valve 38, after whichthe nut 4| can be screwed down into position, as shown in Fig. 7. Thenby tightening up the nut 44 on the lower end of the coupling 35, thepacking rings 46 and 41 will again be made to grip the tube 39 toproperly secure it in aoosition relative to the tube 42 of the couplingAn important feature of the invention is the valve unit and associatedparts of the bung or bushing shown in Figs. 9 to 14, inclusive. In thisconstruction the unit comprising the valve supporting member 72, thevalve thereon, and the enclosing means for the valve can be insertedwithin the opening 69 of the disk 24 and positioned on the tapered seat10 of the disk as shown in Fig. 13. The packing ring 8| for supportingthe tube 40 can then be positioned within the opening upon the upperface of the supporting member ill, after which the ring nut 82 can beapplied and left slightly spaced from the packing ring. The tube 40 canthen be inserted through the opening and downwardly'within the barrel tothe position shown in Fig. 6, after which the ring nut 82 will bescrewed down to cause the packing ring to spread and firmly grip andhold the tube in the desired position, the packing ring at the same timeserving to seal the joint against the escape of the air or gas deliveredto the barrel for exerting pressure on the liquid to effect discharge ofthe same when the faucet is open. It will be seen that the packing ring8| not only serves as a supporting element for the pipe but as a meansfor holding the supporting member 12 of the valve unit in position uponits seat 10.

It will be understood that the upper wall 16 of the compartment a, Fig.2, may, if desired, be used as a platform for the attendant of the bar,or as supporting means for a floor mat or covering on which to stand.

It will also be understood that the valve 85 operates to exclude thebeer from access to the air supply line valve seating member of rubber,or the like, which in the old types of beer dispensing apparatus becomesfoul and contaminates the beer. In the present construction the beer isprevented from coming in contact with the rubber valve seating member 89by the valve 85 and also because of the air pressure maintained in thebarrel for the purpose of discharging the beer therefrom.

By providing glass supply tubes for delivering the beer to thedispensing faucets the barrels may be used for several weeks, whereasthe metal pipes heretofore used contaminate the beer withing a few days.Furthermore the glass tubes will remain clean for many months and thebeer will not be adversely affected thereby.
